Th problem with your line of thinking is, it doesnt take in account of the road vs home difference. Every team has one.
Though every team has a "road vs home difference", there's nothing to prove that the "difference" will stay in place over the course of an entire season, or in this case ... even a shortened season. Your point makes no sense.
For instance, even though the Wings had no PPG's on the road in their first 30 some chances ... you couldn't make a valid conclusion that they'd never score a PPG on the road all season.
Past play is somewhat predictive of future play, but it's impossible to draw absolute conclusions. Look at Columbus. Who could have predicted that they could go 11 or 12 games without a loss? ... but they have.
